The hacker group Rhysida demanded $6 million in bitcoin as ransom
On 24 August 2024, Seattle-Tacoma International Airport (also known as SEA or Sea-Tac) was hit by a cyberattack that disrupted internet and display systems, causing chaos and inconvenience for travellers. The attack was launched at a busy time, just a week before the Labor Day holiday weekend.
The hacker group Rhysida was identified as the perpetrator and demanded 100 bitcoin, valued at around $6 million, as ransom. This group is known to law enforcement agencies for carrying out ransomware attacks on large organisations. They have been observed using external-facing remote services to initially access and navigate within a network, such as virtual private networks (VPNs).
The Port of Seattle, which owns and operates the airport, has refused to pay the ransom. They have released a statement emphasising that it remains safe to travel from the airport and use the Port's maritime facilities. The Port isolated critical systems and worked to restore full service, although there was no estimated time for when systems would return to normal. The attack primarily affected shared systems between airlines, including baggage handling, ticketing, check-in kiosks, and gate information displays.
The airport is still recovering from the attack, with lingering effects remaining. The Transportation Security Administration's (TSA) equipment and computer systems were not impacted, and Customs and Border Protection services continued to operate. The Federal Bureau of Investigation (FBI) is conducting a criminal investigation into the incident, and the airport is collaborating with them to prevent similar attacks in the future.

The attack disrupted ticketing, check-in kiosks and baggage handling
On 24 August 2024, Seattle-Tacoma International Airport (also known as SEA or Sea-Tac) was hit by a cyberattack that disrupted ticketing, check-in kiosks, and baggage handling. The attack was carried out by a hacker group called Rhysida, known for ransomware attacks on large organizations.
The cyberattack affected internet and display systems, causing message boards and screens across the airport to go dark. This made it difficult for travellers to find their gates and flight information. The attack also impacted the airport's ability to send emails and plunged the airport into an operational crisis for several days. Some airlines resorted to manual processes, including using pen and paper to check in passengers and hand-writing boarding passes.
Baggage handling was particularly affected by the attack, with one source noting that it was "getting the worst of it". The disruption caused by the cyberattack led to a backlog of more than 8,000 bags that had to be manually sorted by airline staff.
The Port of Seattle, which manages the airport, confirmed that data was stolen during the ransomware attack. The hacker group Rhysida demanded a ransom of $6 million in bitcoin for the return of the data. However, the Port of Seattle refused to pay the ransom, stating that doing so would not make it "a good steward of taxpayer dollars". The FBI and the Transportation Security Administration are conducting a criminal investigation into the attack and working to prevent similar incidents in the future.

The airport isolated critical systems and worked to restore full service
The Port of Seattle, which includes the Seattle-Tacoma International Airport, experienced a cyberattack on 24 August 2024. The attack was linked to a ransomware gang called Rhysida, which has been known to law enforcement agencies for ransomware attacks on large organisations. The attack resulted in a loss of internet and display systems, including message boards and email services, forcing the airport to isolate critical systems and work to restore full services.
The airport was plunged into an operational crisis, with officials and workers unable to even send emails. However, flights were able to operate, albeit with significant disruptions. Passengers on smaller airlines had to use paper boarding passes, and some airlines had to manually check in passengers, sort baggage, and handwrite boarding passes. The Transportation Security Administration's (TSA) equipment and computer systems were not affected, and Customs and Border Protection services continued.
The Port of Seattle took measures to thwart the attack and ensure the safety of travellers, deploying workers throughout the airport to guide passengers and using various methods to ensure bags reached their aircraft. The TSA also issued emergency regulations in 2023 for airports and aircraft operators to have pre-approved implementation plans for increased security measures. Despite these efforts, public WiFi and display boards with flight and baggage information remained down for more than a week after the attack.
The airport is still working to restore full services and has provided updates on its progress. Volunteers remain on the ground to help travellers, and the airport has advised travellers to complete as much of the preflight process as possible at home, as terminal screens continue to have issues displaying up-to-date flight information. The airport is also working with the Federal Bureau of Investigation and the TSA to determine how the attack was orchestrated and to prevent similar incidents in the future.
